Isicelo somkhiqizo

I-Cephalosporin, esetshenziswa njengendawo ephakathi ye-cefbutan ne-cefazoxime.

ukukhiqiza

I-sulfuric acid egxilile (104.3mL, 1.92mol) yengezwa emabhodleleni amathathu, kwase kwengezwa i-isophthalic acid (40g, 0.24mol), yanyakaziswa futhi yashiswa ibe ngu-60 ℃, ebanjelwe u-0.5h, kanye no-60% nitric acid (37.8g, 0.36) mol) yengezwe ukulawula idigri yokusheshisa amaconsi. Yengeze emahoreni angu-2. Ngemuva kwalokho, ukusabela kokugcina ukushisa ku-60 ℃ amahora ama-2. Phola ube ngaphansi kuka-50 ° C, bese ufaka u-100mL wamanzi. Impahla ipholile ekamelweni lokushisa, ithululelwe esihlungi, iphonswe ukuze isuse i-asidi yemfucuza, ikhekhe lokuhlunga lihlanjululwe ngamanzi, likhishwe ukuze liphinde likhanye, futhi umkhiqizo omhlophe wawungamagremu angu-34.6, isivuno sasingu-68.4%.

Imininingwane kanye nesitoreji

20Kg noma 25Kg/ ibhakede, ibhakede lekhadibhodi, elifakwe ungqimba olumhlophe kanye nesikhwama esimnyama se-polyethylene. 2℃-8℃ indawo eyomile, epholile, kude nendawo yokugcina ukukhanya, isebenza iminyaka emi-2.
